So maybe you're already sold on the virtues of the FG Knot for bass fishing? Or perhaps you're just looking for a stronger knot for LRF, like I was. But you might have thought that the FG Knot wasn't possible with Light Game lines and leaders?
The FG Knot isn't the easiest of knots to tie, but its amazing strength properties mean that a good knot tied at home may well last you an entire day on the water (even with snags, as the line should break at the lure). I thought that the FG wonder-knot was out of reach of 4lb leader and PE0.3 braid, but on discovering the Daiichi Seiko Knot Assist 2.0 on my last trip to Japan, the packaging clearly stated it worked for braids between 0.3 and 6, and leader between 3lb and 70lb. So I threw one in my basket.
It's now a year later and I'm sold on the virtues. It's a complicated knot to tie. I don't think I'd have the patience to tie it if it wasn't for the Knot Assist tool. It makes the process relatively simple, even for someone cack-handed, like me.
Fishing a leader slightly lighter than your mainline braid and using the FG Knot as the connection offers significant advantages. The line will always break at the lure or clip if a standard knot is used here - I use the Uni knot - saving you time retying time-consuming leader knots. Don't be tempted to use heavier leader than your mainline though. I tried this wrasse fishing and when you eventually have to pull for a break, the braid will pop at some random place along the braid - the knot is that strong - normally near the rod tip, I've found. You can get through a lot of braid quickly!
It's not a cheap tool, but equally it is well-made and feels like it will last a lifetime. If you're looking for a solution to tying better knots for LRF, the Daiichi Seiko Knot Assist 2.0 is certainly a good option.
